METAL WINDOW FRAME AND SA-SH;

Patented Jan. 9, 1917.

Specification of Letters Patent.

Application filed July 1, 1916. Serial No. 106,997.

To all whom it may concern Be it known that I, HARRY E. CAMPBELL, a citizen of the United States, residing at New York,.in the county of New York and State of New York, have invented a certain new and useful Improvement in Metal Window Frames and Sashes, of which the following is a specification.

The invention relates to metal windowframes and sashes, and consists in the construction of the meeting rails of two vertieally movable sashes, whereby the same become engaged and a tight joint produced, when said sashes are in closed position, and whereby the joints between the ends of said meeting rails and the jambs of the windowframe are made tight.

In the accompanying drawlngs Figure 1. is an elevation of the middle portion of a metal window-frame, showing the construc-. tion of my meeting sash rails. Fig. 2 is a section on the line as, m of Fig. 1.

Similar numbers of reference indicate lilze parts. c

A portion of one of the hollow jambs of the-frame is shown at 1. At '2 and 3 are vertical openings in the inner wall of the jamb for the reception of guide-plates 4 on the lower sash and 4* on the upper sash, which laterally project from the side rails of the sashes.

5 is the glass pane of the'upper sash, and 6 is the glass pane of the lower sash. Each metal side rail is formed of two bars 7, 8 united and receiving the pane-between them.

The guide-plates 4" entering jamb slot 3 are carried by the outer side rail bars 80f the upper sash. The guide-plates 4: entering j amb slot 2 are carried by the inner siderail bars 7 of the lower sash.

The meeting rails are constructed as follows: The meeting rail of the upper sash comprises a plate 9 bent twice at right angles and extending under the pane 5 and over its lower portion. United to plate ,9, as by electric welding, is a plate 10 which extends over the lower portion of the opposite side of pane 5. Plate 10 is bent inwardly at right angles at 11, and then upwardly to form a flange 12.

The meeting rail of the lower sash comprises a plate 13 which covers the upper portion of the front side of the lower pane 6, and then is bent twice to extend over the top of said pane and form an upwardly projecting flange 14. On the front side of plate 13 is secured a plate 15 which extends above the horizontal portion of plate 13 and then isoutwardly inclined. ,To the-flange 14 is united a plate 16 which extends downwardly to cover the inner upper surface of pane 6, and at its uppeh portion is bent at right angles at 17 to extend over flange 14, plate 15 and flange 12, and then downward and outwardly-to form a flange 18. When the upper sash is in closed position, the flange 12 enters between the inclined upper portion .of plate 15 and flange 18, which parts unitedly form substantially a spring clip which extends longitudinally from end to end of the rail; The joints between flange 12 and inclined clip members 18, 15 are made I tight by the resiliency of said members, and by the same means the sashes are prevented from rattling.

In order to close the joints atthe ends of the meeting rails when saidrails are engaged, I provide on each hollow jamb and between the vertical guide slots 2, 3 therein,

.a block 19 having its upper and lower edge beveled. These blocks bear against the 'vertical, edges of the side rails of the sashes, as well as against the ends of the meeting rails.

I I claim;

1. A window-frame, an upper sash, a lower sash, the said sashes being vertically movable in said frame, and, on the meeting rail of one of said sashes, two separated resilient flanges, one of said flanges being inclined toward the other flange, and, on the meeting rail of the otherv sash, a single flange; the said first-named flanges receiving in the tapering space between them and resiliently engaging the said last-named flange when said sashes are in closed position.

2. A window-frame, an upper sash, a

lower sash, said sashes being vertically movable in said frame, two separated resilient converging flanges on the meetlng rail of' plate and having at its outer edge a down wardly'and outwardly inclined flange, and an upper sash having an upwardly extending flangeenteringbetween-and in contact with said inclined- -plate and said inclined flange" on said lower sash when said sashes are in closed position.

4. A window-frame, two sashes slidable therein, the meeting rail ofeach sash having all parts of each of itsend faces disposed in the same plane, and fixed blocks on the inner sides of said frame, having their exposed faces parallel to the end faces of said rails and placed to make contact with said end faces to'close the jointsloetwe'en said block faces and saidend faces when said sashes are in closed position.

5. A metal window-frame, comprising hollow amhs, each having two vertical guide slots 1n 1ts innerwall, two sashes respec- -tively entering said slots, and, on each of signature in presence of two witnesses.
